Hydrological jump characteristics in a rectangular open channel flume with sluice gates at both ends are the focus of this article. Among many aspects hydraulic that have been examined analytically and experimentally are: (i) Sequent depth relation (y2y1), (ii) Length jump, (iii) Relative loss energy (ELE1), (iv) Water profile jump. There was total 15 inflow tests conducted. With values between...

Water droplets can jump during vapor condensation on solid benzene near its melting point. This phenomenon, which can be viewed as a kind of micro scale steam engine, is studied experimentally and numerically. The latent heat of condensation transferred at the drop three phase contact line melts the substrate during a time proportional to R (the drop radius). The wetting conditions change and a...

Humans achieve greater jump height during a counter-movement jump (CMJ) than in a squat jump (SJ). However, the crucial difference is the mean mechanical power output during the propulsion phase, which could be determined by intrinsic neuro-muscular mechanisms for power production. We measured M. vastus lateralis (VL) fascicle length changes and activation patterns and assessed the force-length...

coronary artery disease is the leading cause of death worldwide. in this study, we compared two surgical methods of left internal mammary artery (lima) anastomosis on left anterior descending (lad) artery in patients with severe diffuse lesions. a total of 40 patients were included in our study and randomly assigned into two groups. in group a, after a long arteriotomy on lad, the posterior sur...

there is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...

The purpose of this study was to evaluate the extent to which residual shank length affects long jump performance of elite athletes with a unilateral transtibial amputation. Sixteen elite, male, long jumpers with a transtibial amputation were videoed while competing in major championships (World Championships 1998, 2002 and Paralympic Games, 2004). The approach, take-off, and landing of each at...

In this paper we explore lattice-based position-jump models of diffusion, and the implications of introducing non-local jumping; particles can jump to a range of nearby boxes rather than only to their nearest neighbours. We begin by deriving conditions for equivalence with traditional local jumping models in the continuum limit. We then generalize a previously postulated implementation of the R...
